Thanks for sharing, many discoveries for me here! Can I propose Nguyen's "Games as the art of agency"? And maybe my own recent work on Order & change in art: royalsocietypublishing.org/doi/10.1098/...

Yes! That would be worth digging into. The counts are normalized by nb of books published, but I also had no idea that the concept is that old. Its use might have morphed though. There is some history in this excellent analysis: harpers.org/archive/2021... Not nearly going that far back though.

I tend to use Google ngram viewer for this (cut-off at 2019 but the trends are clear)
